Many are pleased with their Kisa.
My experience has not been so enlightening as the armguard comes loose after a handfull of shots. The actual developer of the Kisa proposed utilizing mink oil inside the stalls and the leather draw tie. Searched often- on and off for nearly a year until I was succesful in locating some mink oil. The results were still the same.
Do believe if the leather washer was replaced wih a more secure keeper, then the arm guard would work for me.
As previously noted: there are many who have been quite satisfied.
